We study charmless hadronic decays of chargedmesons to the final statesandusing adata sample that containspairs and was collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energycollider. For, the measured branching fraction and directasymmetry areand, respectively. In the absence of a statistically significant signal for, we obtain a 90% confidence-level upper limit on its branching fraction as.
